Newly designed molecular ‘machines’,
chips, drug delivery systems etc
New materials, due to new
materials due to new
configurations, not occurring innature
Application of known substances in

Toxicology
‘Inert’ materials become reactive on
nanoscale
Toxicity depends on size, chemistry and
form
Mostly limited to insolublesubstances
limited to insoluble substances
Knowledge gap
No legislation
>300,000 essentially new materials
Synthetic Biology
Marriage between biotechnology and
engineering principles
iAssembly of biologic ‘machines’ from
elementary building blocks
From artisanal craft to mass industry

Interconnections between nano and
synthetic biology

Similar issues as in nano
Why bother?
Products spread like wildfire
Huge government investments, facilitating
decision-making, lots of economic
opportunities
